DISTRIBUTING ROLL.

Application filed March 31, 1921.

yTo @ZZ whom t may con-cern.'

Be it known that I, ANDREW B. HEEOLD, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Distributing Rolls, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which itr appertains vto mak and use the same.

The objects of the invention are to provide means for enabling a printer to produce spaced impressions upon printed and illustrated matter particularly to apply separate colors similar to the multicolor impressions made for commercial work to the print- A ing rolls and to perform the work, more eX- peditiously and efhciently and with greater possibilities as to the range of color employed than by the present known methods, also by the improved method the limits of the bands of color applied can be accurately determined and varied to suit the requirement of each design to be printed, which can not be accomplished by previous methods. i

The invention comprises the employment of a sectional vibrating roll for distributing the respective colors, in connectionwith the use of integral composition printing rolls having continuous unbroken surfaces.

The vibrating roll comprises a central longitudinally vibrating shaft or mandrel upon which a multiple number of cylindrical sections are adjustably mounted.

These sections are separated from each other by means of spacing members which are adjustably mounted upon the aforesaid shaft.

This construction enables the printer or press-man to employ as many different colors or shades of color as there are cylinders and since gaps are left between the cylinders, no overlapping or blending of colors upon the marginal lines is permitted, also the printing plates or forms canbe placed much nearer together than in the present methods.

The invention further includes the combination and arrangement of parts, hereinafter more fully described, shown in the accompanying drawings, and specifically pointed out in the claims.

In the drawinos Figure 1 is a transverse section of the vibrating roll and the compo- Serial No. 457,212.

sition rolls, vFigure 2 is a side elevation of the vibratingroll, Figure 3 `is a side elevation of one of the cylindrical sections of the vibrating roll, Figure l is an end elevation thereof, Figure 5 is a side elevation of a spacing device for separating thecylindrical sections, of the vibrating roll, Figure 6 is an end elevation thereof.

yIn these views A represents the shaft of the vibrating roll, B, B, are cylindrical sections sleeved thereover and separated by spacing cylinders C, C, which are slidingly movable upon the central shaft, and are prevented from revolving thereon by means of a key D engaging the key yway D shown in Figs. 5 and 6.

The sectional cylinders are provided with the disc shaped heads E, E, having central openings El and key ways E2 through which the shaft and key pass and arranged in spaced pairs on said shaft, each pair of heads being provided with annular flanges E3 E3, on their inner faces, concentric with the outer edges f of said discs.

Upon these flanges rest the tubular cylinders B, B, having their peripheries flush with the edges of the discs as shown in Fig 3, clamping nuts F, F, and washers G, G, securing the sectional cylinders and spacing devices upon the shaft in adjusted positions.

i The cylinders can be made of any length and the spacers of any width to accommodate the widths of the printing plates.

By the use of this invention` all cutting of the composition rollers is eliminated, and since the section cut from composition rollers must be thrown away after one use, an immense saving in the cost of material will be effected. f

Also by the use of the sectional vibrating roller the composition rollers can be continuously used until worn out.

Also heretofore when color printing is done, a composition roller must be cut to apply the color over the width of the column required, but when a sectional vib-rating roller is employed a section can be sef lected of the required width and slid along the shaft to the desired position, and after printing can be removed and cleaned.

Having described the invention what I claim as new and desire to secure by Letters Patent is:

1. In a printing press for color printing, the combination 'with the shaft of a distributingvibrating roll of a key running longitudinally therein, spaced pairs of disc shaped heads having' key Ways and sleeved over said shaft and key, each head provided with an annular flange adjacent to its outer edge on its inner surface, and a hollowT cylinder secured betvveen the heads of each pair of heads and resting upon said flanges, the outer surface of said cylinder being of the saine diameter as its adjacent heads, and removable spacing means for said cylinders, said pairs of heads and said spacing ineans having key ways and sleeved over said ysha'ft and key and adjustable retaining nuts for said` adjusted roll.

' 2. In a printing press Jfor -color printing, the combination With the shaft of a distributing vibrating roll, of a key running longitudinally therein, spaced pairs of disc.

.shaped heads having key Ways and sleeved over said shaft and key, each head provided Willi an annular flange adjacent to its outer edge on its inner surface, and a hollow cylinder secured between the heads of each pair of heads, and resting upon said flanges, the outer surface of said cylinder being of the saine diameter as its adjacent heads7 and independenlmovable spacing means for said cylinders, said pairs of heads having key Ways and sleeved over said shaft and key, and adjusting Ineans upon said shaft for movingA said cylinders and spacers.

.ln testimony whereof, l hereunto set my hand this 16 day of March, 1921.
